If an AR lower says multi caliber, and the rifle is chambered in 5.56, will that lower accept and run a 308 upper?

The AR-15 eats all sorts of shorty rounds all the way up to the 458 Socom & 50 Beaowulf but those rounds are so big, they sit single stack in the same size mag size.
.308 OAL rounds work around an entire different family. Personally, I feel the AR-10 platform is too heavy and bulky.

however I think bruiser got the OP wrong as his answer didnt really apply to the question.
the simple answer to the OP is no ar10 platforms for large calibers like 308 are larger than the smaller ar15 platform of 556
